Vintage 1960s Button Down Robe, Size M

Circa 1960’s Pink Button Down Robe in great vintage condition. Silky type nylon fabric. I’m not sure if it was custom sewn but it is a beautiful piece! 😍 No labels found inside. Approximate length is 55” from top to bottom on mannequin. The approximate bust is 19” across. See photo. I would say it is a size medium because you want little bit of room. Just beautiful and 1 of a kind. I’ve not seen one anywhere else. ❤️
